Siarnaq, Moon of Saturn

Siarnaq is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 108,394,044.13 km. The furthest it gets from its orbital parent (apoasis) is 25,315,240 km. Its mass is estimated/calculated at being 38,965,379,260,527,000 kg. Its density has been calculated at being 2.3 g/cm3. Its volume is 33,510 km3.

Siarnaq was discovered on 23 September 2000 by Brett J. Gladman, John J. Kavelaars, Jean-Marc Petit, Hans Scholl, Matthew J. Holman, Brian G. Marsd.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 895.51 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Semi-Major Axis of the orbit is 18,015,400 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Siarnaq is 125.7 km. The mean radius, that is the average radius of Siarnaq is 20.0 (assuming an albedo of 0.06) km. The surface area of Siarnaq is 5,026.55 km2. The surface gravity of the said item is 0.007 m/s2. The average orbit velocity, that is the speed at which it orbits is 5,038.2 km/h.

The orbital inclination, the angle at which Siarnaq orbits in relation to the orbital plane is 44.507 degrees. The orbital eccentricity is 0.4052, it is the degree at which Siarnaq orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
